DOUBLETBEE AND LINE-HOLDER.

Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed December 16, 1907. Serial No. 406,676.

To all whom it may concern:

Be it known that I, v' lr ALTER A. WILLIAMs, a citizen of the United States, and a resident of Lexington, in the county of Cleveland and State of Oklahoma, have invented certain new and useful Improvements in Double trees and Line-Holders, of which the following is a specification.

This invention is an improvement in double-trees and line holders for use thereon and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawing Figure 1 is a perspective view of the apparatus ready for use, the tongue being broken away in section. Fig. 2 is a cross-section on about line 22 of Fig. 1. Fig. 3 is a cross-section on about line 33 of Fig. 1. Fig. 4 is a detail view of the tongue plate, and Fig. 5 is a detail view of the double-tree plate.

The tongue A, double-tree B, and swingletrees C may in general respects be of ordinary construction. The doubletree B is pivoted by the king bolt D to the pole or tongue A, and the swingle-trees C are 7 ivoted by the bolts G to the ends of the dou le-tree and are braced by the loops C, as best shown in Fig. 3 of the drawing.

The tongue plate A shown in detail in Fig. 4-, is formed with a broad head-like portion A at its rear end perforated for the bolt D and upon which the double-tree rocks in the use of the invention. This head A is bolted securely to the tongue and the plate A extends forwardly to a point in advance ofthe arch rod of the double-tree plate and forms a bearing therefor.

The double-tree plate E has a back plate E secured to the under side of the doubletree, and the forwardly extending arch rod E which slides at its middle portion upon the plate A is preferably shouldered at E on opposite sides of said central portion E to limit the rocking movement of the doubletree, and a cover plate F is secured at its rear end by a bolt D above the doubletree and extends thence forwardly and is bent down to overlie the front end of the tongue plate A, and is bent to form an upwardly curved keeper F in which the central portion E of the arch rod E slides as the doubletree rocks in the use of the invention.

A strap G is secured at its rear end to the rear end of the tongue or pole, and bends upwardly and lies at its front end G upon the double-tree, and receives the king bolt D.

The line holder is in the form of a bar H, extendin longitudinally above the doubletree and iaving at its ends the downwardly projecting portions H having at their lower ends feet H held by the bolts 0 of the swingletrees, the said rod H being supported mid way between its ends by the upright H having its rearwardly deflected foot H secured by the double-tree. This line holder having the intermediate and the end supports, and extending over the top of the double-tree and to the central pivot of the swingle-trees, operates to prevent the lines from getting under the inner ends of the swingle-trees.

The double-tree plate forms a brace for said double-tree and also by its arch rod E a stay, which is especially constructed at its middle portion to cooperate with the tongue plate and the cover plate F in limiting the rocking movement of the double-tree in the use of the invention, While the tongue plate A forms at its rear end a wear plate for the double-tree, as will be understood from the drawing.

1. The improvement herein described comprising the tongue, the plate thereon, the double-tree, the doubletree'plate having a stay plate secured to the under side of the double-tree and a forwardly extending arch rod provided at its middle with the reduced portion sliding upon the tongue plate, a cover plate secured upon the tongue and having a bearing portion overlying the central reduced portion of the arch rod and forming a keeper therefor and provided at its rear end with the upwardly projecting portion overlying the doubletree, the king bolt pivoting the double-tree in connection with the tongue, the swingle-trees, the bolts pivotin said swingle-trees to the double-tree, and the line rod having the intermediate and end depending portions secured by the king bolt and the pivot bolts of the swingle-trees, all substantially as and for the purpose set forth.

2. The improvement in whiifle trees herein described consisting in combination with the tongue and a double tree pivoted thereto, of swingle trees pivoted to the double tree, a cover plate overlying at its rear end the double tree and extending thence forward over the tongue, a tongue plate underlying at its rear end the double tree and extending thence forward over the tongue and underlying at its front end the front end of the cover plate, the latter being deflected to form a guide for an arch rod, the said double tree, cover plate, and tongue plates having alined openings for the king bolt, a king bolt passing through said openings, an arch rod secured at its ends to the double tree and eX- tending thence forwardly over the tongue and operating midway between its ends between the cover plate, and tongue plate, a
